ANTISLIPPING DEVICE.

Specification of Letters Patent.

Pate-ted kpr 25,1911...

Application led October 21, 1910. Serial No. 588,335.

To all whom it may concern.'`

. Be it known that I, OsoAn FALicENwaLDE', residing at Baltimore, in the State of Maryland, have invented certain new and uset'ul Improvements in Antislipping Devices, of which the following is a specification.

My invention relates to certain new and useful improvements in anti-slipping de vices for automobile wheels, and the like, and the invention has for its object to provide an improved form of anti-slipping device which can be'quickly attached to the wheel and in which is provided a clamping" inember to be secured on the spoke ot' the Wheel, the clamping member having arms to embrace the wheel telly, an anti-slipping member to go over the tire tread' and rigid `link arms pivoted to the clamping arms and connected to the anti-slipping member that passes over the face of the tire.

Other advantageous objects ot my invention will be readily apparent to those skilled in the art.

In the dra\vings,1*`ig11re 1,'isv a side elevation of the preferred form ot' my device. Fig. 2, is' a cross section through the wheel, showing my device in elevation, the-parts being in the normal position. Fig. 3, lis a View similar to Fig. 2, showing the tire when compressed by theweight ot' the machine and showing how the rigid link arms prevent cutting the tire and hold the chain or the member that engages the tread ot the tire in its extended position. Fig. 4. is a view Similar to Fig. 2 ol a inoditied forni otthe invention. Fig. 5, is a plan view ot the tread engaging plate ot the. YForm shown in Fig.- t. Fig. (3, is a modiiication ot the tread engaging plate shown in Fig. 5. t and t5, are detail perspective views ot the clamp members separated. Fig. t), is a section on the line $)--'t) of Fig. l.

Referring now to the accompanying drawings, in which like letters and numerals ot reference indicate like parts in all oi the figures, l designates the telly ot the wheel, rl`his rim in the torni shown in Figs. l to il inclusive of the drawings is ot the quick detachable type.

3 designates the tire which may be of any desired'eonstruetionl All oi' the foregoing parts may be ot' the usual construct-ion, as may also be the spokes -tl ot the Wheel.

My invention includes a sectional clamp composed of two sectien. 4 and lil, lthe section 4 including the bodJ that receives the spoke SO, and has arms tori.lx rating in a pair ot apertured ears 5, which n practice lie close up to th.` rim 2 of the wl.eel. The body portion of the elaa'ip'secten av also has laterally projected ears .t5 .it one side, and a tongue 7 at the other side. Between the ears an oye bolt S is mounted, the eye bol* 'e' carrying` a wing nutt) and suitable .vashers lt), as shown.

Secured to th.n body part ot' the clamp sectiontis aleather strap ll which is screwed or otherwise secured at 13 to the clamp section 4t, and then folded back upon itself to cover the screw head and prevent its coming in contact with the spoke 30, the fold being made as shown at 12 in thedrawings, so that the ends 'of thc strap ll will Project beyond the outer` edge ot Ythe rim 2 between the telly or rim 2 and the arms 5 ot' the clamp section et and prevent the parts thereof coming in contact with thev wheel folly andv fwn. The other clamp section let is made veryy similar to the section Il and the body portion of the section 14. has projecting armsv l5 terminating in apertured ears, and it also is provided with a pair of laterally projecting lugs 1G at one end, andan apertured lug` 17 at the other end, through the aperture lb of which the tongue 7 ol the clamp section 4 projects. The eye bolt 8 passes between the lugs-'16 so that the wing nut t) and washers 'IU will rest against the lug 1G and enable the sections '4 and llt to be tightly clamped to the spoke tt).

'lhe clamp section 14 is also provided with a strap 19 which is secured at 2l to the body part oi the clamp section 14 and bent back upon itselt at 2() so that the ends of the strap l) will project beyond the arm la and prevent contact between such arni and the rim parts.

Each ot' the. ears ot the arms 5 and l5 are apertured to receive pins 22 which are held in place by cotters On the pins 22 are pivoted the rigid arm links 25. The links 25 are formed ot a rod bent back upon itseli' to leave a` loop 28, the ends ot the rod 25 being bent into eyes 2G to receive the pins 22 and be hold between the ears ofA the arms 5 and l5, as bestl shown in Fig. l of the drawings. 'lhe bent back portions of the rod 25 lie parallel to one another, and when the invention is to be nsed in connection with quick detachable rims the link arms are transversely bent, as at 9,7, so that they will not come into contact witlithe 'rim parts.

The arms 25 extend toward `the periphery of the Wheel a sulicient distance so that the eyes come approximately haltn Way upon the side of the tire and so that they may connect with the tread engaging anti-slipping meinber, winch in the form shown in Figs. 1 to 3 inclusive of the drawings, consists oi a simple link chain 29.

- together with the body portion of the clamp memlers 4 and '14 serve to form a pocket or channel in which' the felly l of the Wheel rests when'the clamp is secured to the spoke 8'0, and further byusing the straps 11 in the-manner hereinbefore described and dis' closfed in the drawings, it will be noticed that no metallic par-t of the clamp or the screws that secure the straps to the clamp sections can come into contact with the spoke 30 and all danger of marring or injuring the spoke 80 is'thereby avoided.

In the form shown in Fig. 4, the link arms lor rods :25 are straight where they connect with the clamp arms T5 and' 15, and they are linked by link members 31 and 32 to the tread engaging plate 33, the link members 32 passing throughapertures 34: in the tread ymember 33 between the ears 35 thereof.

The tread member 33 may be either of the form shown in Fig. 5, or that shown `in Fig. 6, depending upon the design of the wheel von which the attachment is to be used, a pro- *1 to 3 ofthe drawings.

scrissi Theform of my invention shown in 1*"igs.l

e, 5 'and 6 is best adapted for use on solid tire wheels, although it may also be used on Wheels carryingpneumatic tires, but for wheels of the pneumatic tire type I prefer to use the form of invention sho/wn in Figs.

From .the foregoing description, taken in connection with the accompanying drawings, it is thought the complete construction, operation and advantages of my invention will be readily understood by those skilled in the art to which the invention appertains.

lVhat I claim is:

1. An anti-slipping` attachment for Vehicle wheels comprising a clamping' device to clamp around the spoke of the wheel, said clamping device including projecting arms `to embrace the wheel telly, said arms terminating in apertured ears, a tread engaging member and link rods pivoted between said earsfand connected `to said tread engaging member, said link rods being of a `lengggth to extend substantially half way upon the side of the tire.

v 2. An anti-slipping attachment for vehicle wheels, comprising a clamping device to grip the spoke of the wheel, said clamping device including divergingly projecting arms vto embrace the wheel telly, said arms terminatin'gjn apertured ears,.a tread engaging the plate, link rods pivoted between said ears to move in a single plane, and chain links connecting said plate -to said rods, said rods eX- tending substantially half Way up the side of the tir s OSCAR Witnesses A.V E.
